The Corvus Sector was a sector of the Breegus System in the Polaris Galaxy. The Corvus Nebula was its entrance. There was a space depot in this sector, as well as 4 different moons. It had the least amount of celestial objects in the Breegus System, but it was also the last sector that Ratchet visited. Qwark claimed (during Full Frontal Assault) that a group of Mutant Space Ninjas had been spotted in this sector.
